ELECTRIC RAILWAY.

SPECIFICATION forming part of Letters Patent No; amass June 11, 71895.

Application filed August 15, 1894. Serial No. 520,350. (No model.) I

To all whom it may concern.-

Be it known that I, SEBASTIAN HOENINGER, a citizen of the United States,and a resident of Milwaukee, in the county of Milwaukee, and in theState of Wisconsin, have invented certain new and usefullmprovements inElectric Railways; and I do hereby declare that the following is a full,clear, thereof.

My invention has for its object to automatically and instantly cut-0Eelectric-current from a broken trolley-wire to thereby prevent injury toman or beast that may come into contact with such a wire; and saidinvention consists in certain peculiarities of construction andcombination of parts hereinafter specified with reference to theaccompanying drawings and subsequently claimed.

In the drawings, Figure 1 representsan elevation, partly in section, ofa portion of an electric-railway system embodying my improvements; Fig.2, a view taken on line 2 2 of the preceding figure, and Fig. 3 apartlysectional view on line 3 3 of the first figure.

Referring by letter to the drawings,A represents a lateral arm of a postin a trolley-system electric railway. Bolted or otherwise rigdly securedto the post-arm is a depending yoke B and likewise connected to the yokecentral of the same is a block 0 of hard wood, Vulcanized fiber or othersuitable insulating material. Depending from the insulating block is aloop-like hanger D held in place by bolts or other suitablemeans, and afeedwire branch E is shown extended through the hanger transverse of thesame, said wire being returned on itself.

Pivotally connected to the ends of the yoke B to extend toward thehanger D are elbowblocks F of insulating material, and bent metal platesG are made fast to said blocks to form stirrups for sections H of atrolleywire. The trolley-wire sections are clamped in their stirrups byscrews I engaging the elbow-blocks and meeting ends of said sections lapeach other on the feed-wire branch above specified to thereby completethe circuit.

As a matter of preference, I employ spiralsprings J in connection withthe yoke B and elbow-blocks F pivoted thereto, these springs being undertension when said blocks are in normal position or in other words withtheir and exact description major portions horizontal and below thepivots." The trolley-wire being in sections and hung in the manner setforth there will be a tilt of at least one of the elbow-blocks F in casesaid wire is fractured and thus the -circuit will be broken, this resultbeing assured by the pull of the spring attached to said block.

While I have shown the trolley-wire sections in contact with feed-wirebranches, my invention is just as applicable in those electric railwaysystems that do not employ a feed-wire, but depend on the trolley-wireto conduct/the current, and it will be readily understood from theforegoing that no injury will result to man or beast coming into contactwith a broken section of said trolley-wire, A

inasmuch as the same is dead the instant the break occurs.

' Having thus described my invention, wha I claim as new, and desire tosecure by Letters Patent, is- V 1. In an electric railway system, thecombination of a suspended yoke, an insulated hanger central of thesame, insulators pivoted to the ends of the yoke, and trolley-wiresections secured to these pivotal insulators to normally lap each otherin the insulated hanger, substantially as set forth.

2. In an electric railway system, the combination of a suspended yoke,an insulated hanger central of the same, insulators pivoted to the endsof the yoke, a spring undertonsion between each pivotal insulator andsaid yoke, and trolley-wire sections secured to the pivotal insulatorsto normally lap each other in the insulated hanger, substantially as setforth.

. 3. In an electric railway system, the combination of feedwire-branches, a trolley-wire comprising a'series of meeting sectionslapping. each other on the feed-wire branches, and pivotal supports forthe trolley wire sections, substantially as set forth. V

4. In an electric railway system, the combination of insulated hangers,feedwire branches extending through the hangers transverse of the same,a trolley-wire com prising a series of meeting sections lapping eachother on the feed-wire branches, and

pivotal supports for the trolley-wire sections,

substantially as set forth.

5. In an electric railway system, the comoted to the yoke ends and atrolley-wire comprising a series of sections joined to the pivotalinsulators to lap each other on the feedwire branches, substantially asset forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Wisconsin, in thepresence of two witnesses.
